Power One Aurora Trio Quick Installation Manual page 2

10.
The 7.5 and 8.5 kW power inverter versions are equipped with two independent input channels (and therefore with double maximum power point tracker MPPT), which
can however be connected in parallel using a single MPPT..
Independent channel configuration (default configuration)
This configuration is factory-set and uses both input channels (MPPT) as independent. This requires the jumpers
Input Mode
(supplied) between the positive and negative poles of the two DC input channels not to be installed and the
INDEPENDENT
independent channel mode to be set in the relevant section of the SETTINGS menu.
Parallel channel configuration
07
This configuration uses the two input channels (MPPT)
connected in parallel. This requires the jumpers (supplied)
between the positive and negative poles of the two DC
input channels to be installed and the parallel channel
mode to be set in the relevant section of the SETTINGS
menu.
11.
Check for correct polarity in the input strings and absence of any leakage to ground in the PV generator.
When exposed to sunlight, the PV panels supply DC direct voltage to the inverter.
The inside of the inverter may only be accessed after the equipment has been disconnected from the grid and from the photovoltaic generator.
The inverter is only to be used with photovoltaic units with ground insulated input poles unless accessories allowing grounding of the inputs have been in-
stalled. In this case it is compulsory to install an isolation transformer on the AC side of the system.
• Connection of inputs on the Standard models
The input connections on inverter models that are not equipped with
a DC disconnect switch can be made in 2 different modes, based on the number
of available input channels.
TRIO-5.8 TRIO-7.5
No. of input channels 1 2
DC cable gland 2 x M25
For all inverter models the DC terminal block can be connected by feeding
23
the cables inside the DC cable glands . The cable gland accepts cables of
18
maximum diameter from 10 to 17 mm, while each terminal of the terminal block
accepts a cable with maximum cross-section of 16 mm (1.5 Nm tightening
2
torque).
Unscrew the cable gland, remove the cover, feed a cable of suitable cross-section and connect it to the terminals on the DC input terminal block.
Once the connection to the terminal block has been made, firmly screw the cable gland (7.5 Nm tightening torque) and check the tightness.
• Connection of inputs on models with disconnect switch
The string connections for inverter versions equipped with DC disconnect switch
quick fit connectors (multicontact or weidmuller), placed at the bottom of the mechanism.
The number of quick fit connectors changes based on the number of input channels.
Each input channel is normally equipped with two pairs of connectors for the connec-
tion of two strings.
TRIO-5.8 TRIO-7.5
No. of input channels 1
No. of quick fit connectors 4 (2 pairs) 4 + 4 (2 pairs per MPPT)
Connect all the strings included in the system design and always check the tightness
of the connectors.
If some of the string inputs are left unused, check that all relevant connectors are covered
with caps and install caps where needed. This is necessary to ensure the tightness of the inverter and to avoid damaging the unused connectors so that they can
be ready for later use.
12.
For the connection of the inverter to the grid, you can choose between a star connection (3 phases + neutral) and a delta connection (3 phases).
In any case, connection of the inverter to ground is mandatory.
To prevent electrocution hazards, all the connection operations must be carried out with the disconnect switch
downstream of the inverter (grid side) open and locked.
For all models, connection with the AC output terminal board
The maximum accepted cable cross-section ranges from 13 to 21 mm, whereas each individual terminal of the terminal board accepts
a cable with cross-section of up to 10 mm 2 (tightening torque 1.5Nm).
R S T N G
Unscrew the cable gland, remove the cover, insert the cable of suitable cross-section and connect the conductors
(Neutral, R, S, T and Ground) to the terminals on the AC output terminal board
Be careful not to change round one of the phases with neutral!
Once the connection to the terminal board is complete, screw in the cable gland firmly (tightening torque 8.0Nm)
and check the tightness.
15.
The firmware can be simply updated via the SD Card (4 GB maximum storage)
The most recent firmware version is available in the downloads section of the www.power-one.com Website or upon request to the Power-One Service.
Launch the update while in good irradiation conditions (avoid the dawn and dusk hours)
• Format the SD card using a "FAT32" File System
• Save the (.tib) update file on the SD Card. The file must not be compressed and/or nested inside folders.
• T urn the inverter off by physically disconnecting the AC and DC voltages, as well as any voltage connected to the multi-function relay,
then open the inverter front cover
• Insert the SD Card in the dedicated memory card housing
25
• Commission the inverter as per the procedure described in section 14 of this installation guide
• The inverter display prompts for confirmation to launch the update
The update procedure starts automatically. Do not operate the inverter in any way during the update process
• Once the procedure is completed, the display shows the update results
16.
The accessories can be bought separately and installed directly by a qualified technician or by the installer.
For information on the installation, compatibility and use of the accessories, refer to the relevant part documentation.

The inverter commissioning procedure is as follows:
• Close the AC disconnect switch to supply the inverter with the grid voltage
• Close the DC disconnect switch to supply the inverter with the photovoltaic generator voltage.
TRIO 7.5/8.5kW (2 MPPT) If the inverter is equipped with a DC disconnect switch (-S models), turn the DC disconnect switch
• When the inverter is connected to the power supply, the display will show a guided configuration procedure. Press ENTER to set the following:
On Field Setup
ENTER to START
Once the guided configuration is completed, the inverter restarts to apply the parameter settings
• When the inverter has power, the first check performed is the one relating to the input voltage:
- If the DC input voltage is lower than the Vstart voltage (voltage required to begin the inverter's grid connection) the b14 icon remains off and the "Waiting sun" message
MPPT1 MPPT2 is displayed b10.
MPPT1 MPPT2
- If the DC input voltage is higher than the Vstart voltage the b14 icon is displayed and the inverter goes to the next stage of the controls.
In both cases the voltage levels and input current are displayed in the b15 and b16 fields.
• The inverter performs a control of grid parameters. The b22 icon, which represents the grid distribution, can have different statuses:
- not present, if the mains voltage results as absent.
- flashing, if the mains voltage is present but outside the parameters dictated by the standard of the country of installation.
- turns on, if the mains voltage is present and within the parameters dictated by the standard of the country of installation. In this condition, the inverter starts the
sequence of grid connection.
If the input voltage and the grid voltage are within the inverter operating intervals, connection to the grid will commence. After the inverter is connected, the icons
05
on the whole line b21 will come on
Once the connection sequence has been completed, the inverter starts to operate and indicates its correct operation by making a sound and by the green LED co-
ming on steady on the LED panel
